Discovery of a Highly Active Catalyst for Hydrogenolysis of C-O Bonds via Systematic, Multi-metallic Catalyst Screening

Paul Joseph Dyson, Ning Yan, Antoine Philippe Van Muyden, Sviatlana Siankevich

Hydrogenolysis of C-O bonds is a highly challenging reaction with the most efficient catalysts based on bimetallic assemblies. Systematic studies to identify the optimum metal combination have not been performed and, therefore, we designed a method to scre ...

Relationship between structures and activities of supported metal vanadates for the selective catalytic reduction of NO by NH3

Oliver Kröcher, Adrian Marberger, Davide Ferri

Transition and rare earth metal vanadates are potential active phases for the selective catalytic reduction (SCR) of nitric oxide by ammonia for exhaust gas emission control. In this work, various metal vanadates mixed with SiO2-WO3-TiO2 (TWS) were compare ...

Synthesis of molecular complexes for small molecule activation

Julie Renée Michelle Andrez

The redox chemistry of f-elements is drawing the attention of inorganic chemists due to their unusual reaction pathways. Notably low-valent f-element complexes have been shown to be able to activate small molecules such as CO2 and N2 in mild conditions. Co ...

Mimicking Enzymatic Active Sites on Surfaces for Energy Conversion Chemistry

Klaus Kern, Sebastian Stepanow, Magalí Alejandra Lingenfelder

Metal organic supramolecular chemistry on surfaces has matured to a point where its underlying growth mechanisms are well understood and structures of defined coordination environments of metal atoms can be synthesized in a controlled and reproducible proc ...

Development of a hyphenated analytical methodology for the fractionation and characterization of environmental colloids

Enrica Alasonati

Natural colloids are defined as macromolecules and nanoparticles with sizes ranging between 1 nm and 1 µm. Colloidal pool is complex "ill-defined" mixture of humic substances, exopolymeric substances (EPS), inorganic oxides, clays, etc. Aquatic colloids ha ...

Metal-organic coordination interactions in Fe-Terephthalic acid networks on Cu(100)

Klaus Kern, Giovanni Costantini

Metal-organic coordination interactions are prime candidates for the formation of self-assembled, nanometer-scale periodic networks with room-temperature structural stability. We present X-ray photoelectron spectroscopy measurements of such networks at the ...

Novel catalytic applications of carbon nanofibers on sintered metal fibers filters as structured supports

Marina Ruta

Supported metal catalysts are important from both an industrial and a scientific point of view. They are used, amongst others, in large-scale processes such as catalytic reforming, hydrotreating, polymerization reactions and hydrogenations. Often, these ca ...
